Lampshades made from seaweed composite

Brand: Tŷ Syml

Applications: Lighting

By combining seaweed with recycled waste paper, Tŷ Syml has created a bio-material that is 100% sustainable and adds value to the environment. The material formed from this combination is tough and durable with a texture similar to cork. It is tactile and possesses a natural warmth, with subtle smells of the sea. Different varieties of seaweed can be used to produce different colours and different characteristics.


There are a number of accreditation assessments available to manufacturers. Set by third party organisations such as BREEAM, LEED, UL and C2C, they offer prospective specifiers the opportunity to understand and evaluate what sustainability standards a given material may offer their project.

Wherever possible we showcase materials that have some form of accreditation but also recognise that acquiring them can be a costly and time consuming process, particularly for smaller brands.

We believe in transparency and think that an honest approach to materiality is key to making more sustainable decisions when planning our built environments.

We seek and promote material manufacturers that:

  • Consciously endeavour to choose raw materials based on provenance and quantity required
  • Aim to reduce the energy needed and pollution created in the production and transportation of their materials
  • Reuse resources and waste
  • Create regenerative materials
  • Utilise closed-loop production methods
